Regarding database migration and server hardware.
Hi Experts,
We have Oracel 10g database running on HP-UX 11i V1 on RP7400 server i.e. PARISC architecture. We are planning to do database migration from Oracle to MaxDB. But we are also planning to upgrade the server i.e. new server which is having ITANIUM architecture and also planning to upgrade the HP-UX operating system version from HP-UX 11i V1 to HP-UX 11i V3.
Please let me know how to proceed with this migration?
Thanks,
Narendra
> You just export the database (selecting maxdb that he copies the nessesary ddl files) and then install you new system.
> After that you can use sapinst to install / load the sap system using the export.
One may need to use table splitting (dowtime reduction), one may need special load arguments for R3load, SMIGR_CREATE_DDL etc. - so it's not as easy as just exporting and importing

Database Migration and OS Change
Hello
I need to migrate database from Windows to Linux. The current size is ~50GB.
Current Env:
OS = Windows 2003
DB version = 10.2.0.3
Proposed Env:
OS = Linux
DB version = 11.2.0.2
Would using datapump be a correct choice for this migration? Also do the step below seem correct?
01. Pre-create tablespaces on target 11g database
02. Export full database of source 10g database
03. Copy dumpfile to Destination Server
04. Grant IMPORT_FULL_DATABASE system privilege to user SYSTEM of target 11g database
05. Import full database to target 11g database
Thank you.Hi may be your approach will very slow. you can also update by in 2 steps
1. Oracle database conversion from oracle 10g (window) to Oracle 10g (Linux)
2. UPDATE 10G TO 11G on linux
Note: Direct conversion method is not possible though Window oracle 10g to Linux Oracle 11g.
if you followed the above approach then your version should be atleast 10.2.0.4 and should be same on both side machines. Experts correct me if i am wrong....

Database Migration and upgrade
Hi,
We are planning to migrate the data center to new location. The new data center already have the hard ware. We have to move the data dump and upgrade the Database. Our most DB are on Oracle
10g Solar UNIX and the new hardware is on Oracle 11.2.0.4 with Linux (Oracle or Redhat Linux). The following activity needs to be done:
1) Taking the export on existing database.
2) Moving the export dump to new location, along with the archived data which is stored in the tape. (this is where a suggestion required most on different ways of doing that).
3) Importing and upgrading the database in new location.
Could some one please suggest the strategy and helpful tool which for performing this activity.Are you expected to move all 100+ databases in a 48 hour window with datapump ? That is a tall order
What is the network capacity (i.e. how fat is the pipe) between the two locations and how far apart are they ? Typically, there should be no data loss or corruption when transferring files over a network. The time required to move/upgrade a 300G database can only be determined by performing a test upgrade that closely resembles production environment.

Regarding Database migration to external storage
Hello.
We are running on MS windows 2003 enterprise edition with Oracle Database 10g.
We have system with 32GB RAM and 600 GB Harddisk space on system, and we have installed SAP Solution manger and SAP Netweaver (PI) 7.0 componenet on that box. At this time we do not have external storage so we segrigate and installed SAP Solution Manager and SAP Netweaver(PI) on same box like
C:\ 120 GB Space - Contains SAP Software and Oracle Database Software
D,E,F and G: drive contains 120 GB each on every drive, which contains oralce database - SAPDatas, oraarch,saparch,sapbackup,sapcheck etc.
Now we have storage with good capacity, so we want to move all data from D,E,F and G: drive.
So how can we to migrate oracle database software to Storage.
Waiting for your kind response.

Regarding database migration from Oracle to MS SQL
Hi All,
In my application, the existing database is oracle. we need to migrate from Oracle db to MS SQL.
We need procedure is as below
1.export data from Oracle and keep it in a file.(.dmp)
2.Import data to MS SQL from the exported oracle file.
and vice versa from MS SQL to Oracle.
my question is- is it possible to import .bmp (oracle export data) into MS SQL.
Please clarify me.There are couple of options to get data from Oracle to MS SQL.
The simplest is to create a linked server in MS SQL that points to Oracle and copy data with a query like select * into my_mssqlTable from oracle.schema.table; via the linked server.
Some data types will not be supported.
That is for one time copy.
If you need a close to real time replication you can use MS replication (I would not recommend because it creates triggers on Oracle tables), or you can use GoldenGate or DataCurrents or other replication products. -
Database Migration and Cross platform migration
Actually I am searching solution for following situation: as follows
Server Name A :
Operating System : IBM AIX
Database Version Oracle 10.1.0..0
No. of Database Instances on this server ….. 2 Databases
Server Name B
Operating System : HP Unix
Database Version Oracle 10.1.0.0
No. of Database Instance on this server ……. 1 Database
And the Target is as follows
We want to migrate above mentioned 3 databases from Server A and B to the new HP-Unix server as follows
New Server details
Operating System : HP Unix 11
Database server : Oracle 10g 10.2.0.2 R2
So can some please give the steps to follow to migrate existing 3 databases to the new server
Thanks,
AmolTake a Full Metadata Datapump Export from the Source Database.
Use SQLFILE option to generate the SQLfile.
Exeute the same in Target Database.
Take a datapump export of Source database with Data and import into Target with EXCLUDE=INDEX,CONSTRAINT,TRIGGERs option.
Create the indexes and other objects after the Datapump import.
Re-compile the Invalid Objects.
You can even perform this using Network_link option.(no need for export dump at file system level if used). You should have better network connectivity between two servers.

Following instructions for downloading Adobe Extension Manger and looking for the .zxp or .xzp files doesn't work with my CW 2014.1 CC. There are NO files with those extensions anywhere in my program folders. This is frustrating being a new customer. I PAID lynda.com for turtorials, after I PAID Adobe for software and now I'm at a standstill. Apparently Adobe doesn't want to talk to their end-users. Has anyone else had this problem? I desperately need to get php and Mysql working for one of my paying customers.
I was pointed in the direction of using PHP and MySQL for database development
PHP and MySQL are correct, but the connection between them should be through mysqli or PDO, not the mysql extension used by Dreamweaver server behaviors.
There are many good tools for creating database powered websites, but it can be done with just Dreamweaver and the tools included with the free XAMPP software package. That package contains the Apache web server, MySQL, PHP and PHPmyAdmin (which is a database interface).
Get the book PHP Solutions by Powers. It will get you going. -
Why Dreamweaver CC delete Databases, Bindings and Server Behaviors (PHP/MySQL)
I installed Dreamweaver CC on my laptop and notice that Dreamweaver CC has no Binding, Server Behaviors and Database.
A lot of my project get done by these feature (Binding, Server Behaviors and Database.), mostly for the website mock up for my clients.
Why Dreamweaver these features? We need these feature back...
For the liquid layout I don't like it, I prefer to use bootstrap then Dreamweaver feature.
Dreamweaver CC just change Dreamweaver into CSS editor comparing to previous version.I'm not a spokesperson for Adobe. I just use the products.
DW CC extensions use .zxp files. Formerly, CS extensions used .mxp files. It's imperative that you use the correct Extension Manager version for your version of DW.
CS5 = CS5 extension manager
CS5.5 = CS5.5 extension manager
CS6 = CS6 extension manager
CC = CC extension manager and so on...
http://www.dmxzone.com/go/21842/enable-server-behaviors-and-data-bindings-panel-support-fo r-dreamweaver-cc/
There have been exhaustive discussions in this forum about the deprecated server-behaviors and Adobe's decision to remove them from CC -- presumably to discourage people from using them anymore. If you want to continue using SBs, do so at your own risk since Adobe no longer officially supports or endorses them. And if you can't get the extension from DMZone above to load in CC, your fallback is to use CS6.

Regarding database relationship and traversing
Hi,
I need algorithm for finding the path by traversing through the database(by the existing relationships between the tables) to attain a particular table for any given table in the database.
My scenario :
Eg :
Say the particular table i.e to be tracked is 'MyTable'.
A small sample hierarchy whithin the database : Say TableA and TableB are the parent tables of 'MyTable'. TableB, TableC, TableD ... can be some of the tables that are child tables of TableA and TableB at some hierarchical levels.
Say given TableD(starting point), I need to find the path by the relationships existing in the database to track the table 'MyTable'
Is there any generic algorithms available for this ? Please advice.Thank you very much. can sql developer get parameters when client application runs. I mean If I can get paramters when client application runs and I don't need to debug client applications. Then I debug stored procedure using those parameters. Thanks.

We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?You will need much more which suggestions.
You will need a Siebel professional which has done this type of migration. Migrating the Database is not a task so hard, after migrating your environment should be functional and healthy it is usually the task problematic.
The hardware can be changed if needed. Can you please suggest the best approach ?We can recommend the minimum recommended, but this documentation already does, you need to do a analysis on your environment and ask a vendor Siebel tell the which is recommended for you and how to find the best "number" for you, in your case is very hard because everything changes.

Server 2012 r2 live migration fails with hardware error
Hello all, we just upgraded one of our hyper v hosts from server 2012 to server 2012 r2; previously we had live replication setup between it and another box on the network which was also running server 2012. After installing server 2012 r2 when a live migration
is attempted we get the message:
"The virtual machine cannot be moved to the destination computer. The hardware on the destination computer is not compatible with the hardware requirements of this virtual machine. Virtual machine migration failed at migration source."
The servers in question are both dell, currently we have a poweredge r910 running server 2012 and a poweredge r900 running server 2012 r2. The section under processor for "migrate to a physical computer using a different processor" is already checked
and this same vm was successfully being live replicated before the upgrade to server 2012 r2. What would have changed around hardware requirements?
We are migrating from server 2012 on the poweredge r910 to server 2012 r2 on the poweredge r900. Also When I say this was an upgrade, we did a full re install and wiped out the installation of server 2012 and installed server 2012 r2, this was not an upgrade
installation.The only cause I’ve seen so far is virtual switches being named differently. I do remember that one of our VMs didn’t move, but we simply bypassed this problem, using one-time backup (VeeamZIP, more specifically).
If it’s one-time operation you can use the same procedure for the VMs in question -> backup and restore them at new server.
Kind regards, Leonardo. -
We are getting ready to migrate from server core 2008 r2 hyper-v with failover cluster volumes on an iscsi san to server core 2012 r2 hyper-v with failover cluster volumes on a new iscsi san.
I've been searching for a "best practices" article for this but have been coming up short. The information I have found either pertains to migrating from 2008 r2 to 2012 r2 with failover cluster volumes on the same hardware, or migrating
to different hardware without failover cluster volumes.
If there is anyone out there that has completed a similar migration, it would be great to hear any feedback you may have on your experiences.
Currently, my approach is as follows:
1. Configure new hyper-v with failover cluster volumes on new SAN with new 2012 r2 hostnodes and 2012 r2 management server
2. Turn off the virtual machines on old 2008 r2 hyper-v hostnodes
3. Stop the VMMS service on the 2008 r2 hostnodes
4. copy the virtual machine files and folders over to the new failover cluster volumes
5. Import vm's into server 2012 r2 hyper-v.
Any feedback on the opertain I have in mind would be helpful.
Thank you,
RobHi Rob,
Yes , I agree with that "file copy " can achieve migration.
Also you can try "copy cluster wizard " :

SBS 2008 - SBS Console and AD errors after migration to new hardware
Hi there,
I'm trying to work out how to fix some of the errors and random behaviour I'm experiencing with the SBS 2008 console and AD related matters since I had to quickly migrate SBS 2008 to new hardware using Windows Server Backup after a failure of the old server.
In my haste to get our email and ftp services back up and running (which use Smartermail and Filezilla respectively instead of Exchange etc) I overlooked the fact that the new server had 3 NICs installed and not one and so restored SBS 2008 and loaded up new
drivers for those and other hardware that had changed (such as the graphics card and mobo. I have since removed the two additional NICs by disabling them on the mobo).
Whilst I got the server up and running again with email and ftp services, even though I currently don't use any AD related stuff directly I have since noted that if I try to say view a list of users that I had previously created via the SBS console, more often
than not it will show no users, and then randomly it will (but when you do see them you can't edit or delete them. I'm aware that I have probably broken a number of golden rules in doing this 'migration' but having a metaphorical gun to my head meant that
I rushed things out of desperation.
Common errors that I experience generally will say things like 'Current security connect is not associated with an Active Directory domain or forest' if I try to list users, or DC not found for domain "xyz.local' etc. I have been searching the net and
trying out some things to fix this but I'm like a dog chasing its tail as I'm not so clued up on server related issues as I am with workstation problems, so if anyone could at least point me in the right direction I would be very grateful. If you require any
info from me (eg diag logs etc) I will be happy to provide them!
Regards,
DaveHi Dave,
Based on current situation, please run SBS BPA and fix all that it can find, then monitor the result. For more details, please refer to the following KB.
Windows SBS Best Practices Analyzer (BPA)
Meanwhile, please refer to the following article and repair SBS console.
Repair the Windows SBS 2008 Console
By the way, I noticed that you had got some error messages (such as: “DC not found for domain” and so on). Would you please let me know complete error messages? In addition, when you migrate SBS 2008 to the new hardware, had you done any preparation for
that Source Server? For more details, please refer to the following article.
Migrate Windows Small Business Server 2008 to New Hardware
If any update, please feel free to let me know.
Hope this helps.

Migrating SQL Server database to Oracle 8i - any known issues
Hi,
I am in the process of migrating SQL Server database to Oracle 8i for testing purpose.
When I do migrate SQL Server database to Oracle 8i, am I doing any harm to the exiting
SQL Server database? Would the users be able to use SQL Server database as usual?? Are
there any known issues in this regard?
Please reply.
Thanks.

Ramesh Hi Ramesh!
The Migration Workbench does not make any modifications to the SQL Server database. It only reads information from it. Your users should be able to use the SQL Server database as usual.
Please note however that if you migrate the data over to Oracle using the Migration Workbench and your users continue to enter/update data in the exiting SQL Server database then you may need to move all that data over again in order to have the most up to date data in the Oracle database.
thanks
